Specification of Letters Patent.

Patented Apr. 8,1913.

To all whom it may concern:

Be it known that I, EDGAR R. LOWEREE, a citizen of the United States,residing at Baltimore, State of Maryland, have invented certain new anduseful Improvements in Beds, of which the following is a description,reference being had to the accompanying drawing and to the figures ofreference marked thereon.

The invention relates to new and useful improvements in beds, and moreespecially to beds which are adapted for invalids or for performingminor operations.

An object of'the invention is to provide a bed construction wherein theportion thereof for supporting the person may be bodily adjustedvertically or wherein one end may be raised and the other end depressed.

A further object of the invention is to provide a bed of the abovecharacter wherein the support for the person may be swung relative tothe bed frame about a central pivotal point A further object of theinvention is to pro-' videa bed of the above character wherein thesupporting portion for the person is formed in sections, certain ofwhich may be adjusted angularly relative to the other.

These and other objects will in part be obvious and will in part behereinafter more fully described.

In the drawings, which show by way of illustration .one embodiment ofthe invention: Figure 1 is a perspective view of a with the supportingportion in raised position. Fig. 3 IS a plan view of the'bed showing thesupporting portion turned at an angle to the bed frame. Fig. 4 is adetail in section showing the pivotal sup'port connecting the supportfor the mattress to the supporting frame therefor. Fig. 5 is a detail inside elevation showing one end of the mattress support raised and theother end depressed.

In carrying out my invention I have provided a bedstead frame which isof the usual construction, consisting ofa head frame 1, a foot frame 2,and side frames 3, 3. These parts may be secured together in any desiredway so as to form a rigid structure. Mounted on the bedstead frame is amattress support 4, on which rests a mattress 5. This mattress is madeas herein shown in three sections 6, 7 and 8. The central section 7 issecured to the mattress support by a pivot pin 9. The section 6 of themattress has two side bars 10 rigidly fixed thereto.

These side bars project beyond the section 6 and are pivoted at 11 tothe section 7 of the mattress. Likewise side bars 12 are rigidly securedto the section 8 of the mattress and project beyond the same and arepivoted at 13 to the section 7 v The sup-porting frame 4 for themattress is preferably formed of angle iron and con sists of side andend bars which are rigidly attached to one another and also flatcrossbars which are suitably spaced and riveted to the horizontalmembers of the side bars forming the mattress support. As clearly shownin Fig. 5,- the sections of the mat tress may be swung to variousangular positions relative to each other. The section 6,

as shown in this figure; is swung about the pivotal connection 11 and isheld in angular or raised position by asupporting bail 14 which ispivoted to the outer end of the section 6 and rests on the mattresssupporting frame. A wire handle 15 may be secured to the outer end ofthe section 6 to facilitate the raising and lowering of the same. Inthis figure the section 5 of the mattress is swung about the pivot pins9 and is held in this angular position by the lower end or edge of thesection 8 of the mattress which. rests on the supporting frame. It willbe obvious that other adjustments of the sections of the mattressrelative to each other and the supporting frame may be made.

While I have used the term mattress, it will be understood that thisterm is used in its broadest sense and is intended to include the use ofcoveredspring sections, tufted felted sections, or any other desiredform of-cons'truction.

The mattress support 4 is carried directly by a supporting frame 16which, as herein shown, is formed of angle bars or irons which arerigidly attached together. Said frame also includes a crossbar 17 whichis rigidly secured at its outer end to the crossbar forming a part ofthe supporting frame. These angle bars are. so shaped that the upperedgesof the vertical flanges lie in a horizontal plane. The mattresssupport is attached to this supporting frame by apivot bolt 18. Thispivot bolt extends through the central crossbar secured to the mattresssupport and also through a central crossbar 17 carried by the supportingframe. A sleeve 19 encircles the pivot bolt and forms a rest for thecrossbar of the mattress support, as shown in Fig. 4. A nut 20 isthreaded onto the pivot bolt 18 and retains the mattress support on thesupporting frame. This connection between the mattress support and thesupporting frame permits the mattress support to be turned about thepivot bolt 18 as a center. The upper edges of the angle bars forming thesup porting frame 16 engage the crossbars on the mattress support andserve as a means for preventing the tilting of the mattress support onits pivot. In other words, the mattress support 1 rests on the frame 16and the pivot bolt 18 merely serves to guide the mattress support as itis swung on the frame and also holdsthe mattress support on the frame.

While I have shown the supporting frame 16 as rectangular, it will beobvious that this frame may be made circular or any other shape. While Ihave shown a pivot bolt for connecting the mattress support to the frame16, it will also be obvious that othgr forms of pivotal connections maybe use The supporting frame 16 is connected to the bedstead-frame bydevices which may be used for bodily raising and lowering saidsupporting frame relative to the bedstead frame. These devices in thepresent embodiment of my invention consist of two E parentthat the frame16 is pivotally conpairs of parallel links or bars 21 and 22. The links21 and 22 atone side of the bedstead frame are secured to the same pivotbolt 23, while the links 21 and 22 at the opposite side of the bedsteadframe are secured to a similar pivot bolt 23. The lower ends of thelinks 21 are connected to a crossbar 24: which projects beyond saidlinks. Aninclined track or guide 25 is attached to the bedstead frameand the projecting end .of the rod 24. extends into said track or guide.There is a similar guide or track for each end of the rod 24. This guideis formed of. a U-shaped bar which is secured at one endto the sideframe of the bed. Said guide is arranged at an angle to the side frameand its other end is attached to the head frame of the bed at a pointbelow the attachment of the side frame thereto. The links 22 areattached to a crossbar 26. The ends of the crossbar project beyond thelinks 22 and engage tracks or guides 27 which are similar in shape tothe guide 25, but incline in opposite directions thereto.

The supporting frame 16 is raised by drawing the ,crossbars 25 and 26toward each other along the supporting guides or tracks therefor. Themeans for moving the rods 25 and 26, as herein shown, cons1st of acenframe.

sesame tral shaft 28 which is mounted'in suitable brackets 29 carried bythe side frames of the bed. This central shaft is formed with laterallyprojecting arms 30 and 31. There are two arms 30 and these arms arelocated adjacent the outer ends of the shaft but inside the supportingbrackets therefor. There are likewise two arms 31 which are similarlydisposed. Each arm 30 is iconnected by a link 32 to the crossbar '26,while each arm 31 is connected by a link 33 to the crossbar 2 1. It willbe apparent that when the shaft 28 is rotated so as to move thelaterally projecting arms from. a horizontal position, as shown in Fig.1, to a vertical position, as shown in Fig. 2, that the cross ars 25 and26 will be moved to- Ward each other and thus raise the supporting frame16 bodily from the bedstead When the shaft 28 is turned in an oppositedirection the crossbars 25 and 26 ,will be moved away from each otherand allow the supporting frame 16 to be lowered. As a means for holdingthe shaft 28 in varigous positions I have provided a ratchet wheel 34. Apivoted locking pawl 85 is adapted to engage the ratchet wheel and holdthe shaft 28 from rotating. The lock- 'ing pawl 35 is provided with afinger piece .36 which projects below the side frame of 'the bed andserves as a handle for throwing the pawl outof engagement with theratchet wheel. Each end of the .shaft 28 is ;formed with a squared Itoreceive a crank 38.

portion 37 adapted From the above description it will be apnected withthe links 21 and 22. In order to hold this framefrom turning about thispivotal connection, I have provided a pair f links 39 which are pivotedat one end to the supporting frame, and at their other end to the outerend of the arms 31. "are so disposed relative to the links for rais-These links ing and lowering the supporting frame as to hold saidsupporting frame in substantially horizontal position when raised andwhen in lowered position. The links will also hold this supporting framesubstantially horizontal while it is being bodily raised from loweredposition to raised position. I have, therefore,.provided means forbodily raising the mattress support from the bedstead frame to raisedposition without tilting the same or without moving the same endwiserelative to the bedstead frame. When the supporting frame is either inlowered position or in raised position the mattress support may be swungabout its pivotal connection therewith. When in lowered position theends of the mattress support will swing between the bars forming the endframes. Furthermore, it will be noted that when the supporting frame isin lowered position, as

shown in Fig. 1, the crossbars 24 and 26 have moved downthe inclinedtracks or supporting frame and depress-the other, the

shaft 28 is turned in a reverse direction from the position shown inFig. 1. This movement of the shaft 28 carries the laterally projectingarms 29 below the shaft and as the links 39 are pivoted to the outerends of these arms 29 the end of the frame 16 to which the links 39 areattached will be held down or depressed, while the central portion ofthe frame 16 will be raised, which results in a tilting of the frame 16,as shown in Fig. 5. The links 39 are each formed with a deflectedportion 40 which permits. this swinging of the arms 29 without the linkscoming into contact with the operating shaft 28.

From the above description it willbe ap-' parent that I have providedjabed construction which consists of few parts and-which can, therefore,be cheaply made and easily kept in order. This bed construction alsopermits of the bodily raising and lowering of the supporting portion forthe person and also the swinging of this supporting'portion at anangleto the bed frame. By these adjustments the supporting portions of thebed for theperson may be quickly adjusted for such conditions as mayarise either in a.

case of sickness or in the performing of minor operations. V

It is obvious that minor changes in the details of construction andarrangement of the parts may be made without departing from thespirit ofthe invention as set forth in the appended claims.
